In an attempt probably to close the mom and pop stores on Taraval Street, there was at one time as many as 8 or 9 chain groceries on Taraval Street from 15th Avenue to 33rd Avenue.MacMar, Piggly Wiggly, Purity, Safeway and I believe another whose name skips my memory. There were if I remember correctly 3 Safeways. Piggly Wiggly was on the north side of the street between 20th and 21st Avenues.MacMar was next to the Associated Gas Station near 26th Avenue. But all except a couple of Safeways were closed.
